	Grebes
		Grebes are members of the Podicipediformes order, a widely distributed order of freshwater diving birds, some of which visit the sea when migrating and in winter.
		Colombian Grebe, Podiceps andinus - extint (1977) : The Colombian Grebe (Podiceps andinus), was a grebe found in the Bogotá wetlands in the Eastern Andes of Colombia.
		The decline of the Colombian grebe is attributed to wetland drainage, siltation, pesticide pollution, disruption by reed harvesting, hunting, competition, and predation of chicks by rainbow trout (Salmo gairdneri) (del Hoyo et al.

		Grebes have narrow wings, and some species are reluctant to fly; indeed, two South American species are completely flightless.
		The grebes are a radically distinct group of birds as regards their anatomy.
		Grebes suddenly appear in the fossil record in the Late Oligocene or Early Miocene, around 23-25 mya.

	IUCN
		Because of grebes' sensitivity to changes in the trophic webs of wetland ecosystems, grebes could be used as indicators of such changes, and as symbols of the struggle to restore these ecosystems.
		Furthermore, by indicating how grebe populations are influenced by changes in the trophic webs of wetlands, it highlights the potential importance of demographic data on grebes in monitoring the health of these ecosystems.
		Grebes may be particularly useful as bioindicators for the planning of wetland management in the western Palearctic, Manchuria, western North America, southern South America, and the Andes.

	Annotated List of the Seabirds of the World - Grebes
		In non-breeding plumage, Pied-billed Grebes are relatively drab.

		At least three species (Alaotra Grebe of central Madagascar, Colombian Grebe of Lake Tota on the Colombia-Venezuela border and Atitlan Grebe of Guatemala) have already or soon will become extinct and others are critically endangered.

	Travel Tips - Travel Information about Colombia
		Colombians customarily describe their country in terms of the climatic zones: the area under 900 meters in elevation is called the hot zone (tierra caliente), elevations between 900 and 1,980 meters are the temperate zone (tierra templada), and elevations from 1,980 meters to about 3,500 meters constitute the cold zone (tierra fría).
		The mean temperature ranges between 10°C and 19°C, and the wet seasons occur in April and May and from September to December, as in the high elevations of the temperate zone.
		Colombian cuisine consists largely of chicken, pork, potato, rice, beans and soup.

	Grebes
		Even when grebes are found on open water, they have a habit of diving for usually long periods of time, surfacing a distance from where they submerged.
		The Red-necked Grebe Podiceps grisegena is one of several grebes restricted to the Northern Hemisphere.
		Hence the reason why grebes are virtually tail-less.They usually winter south of their breeding range, tending to stay clear of frozen lakes.

	Grebe page
		The grebes are an ancient family going back 80 million years, well-represented in the fossil record, and not closely related to any other birds (Llimona and del Hoyo 1992).
		Although there are five genera in the grebes, each is basically a variation on the same theme, and it is always easy to tell that a grebe is a grebe.
		The North American grebes of the genus Aechmophorus are an interesting study in the biological species concept.

	Federal Register: Part II [50 CFR Part 17]
		The Colombian grebe was formerly considered abundant on Lake Tota in the 1940s, but by 1968, it had declined to approximately 300 birds (del Hoyo et al.
		The Junin grebe is a bird of open lake habitat and stays far offshore in the center of the lake for part of the year.
		Current population estimates for the Junin grebe are between 50 and 249 birds, with a decreasing population trend (BirdLife International 2000).

	Grebe (Site not responding. Last check: 2007-11-03)
		Grebes are small to medium-large in size, have lobed toes, and are excellent swimmers and divers.
		However, they have their feet placed far back on the body, making them quite ungainly on land.
		The grebes share anatomical characters with and are genetically most closely related to flamingos Phoenicopteridae, in spite of their superficial differences.

		With the great improvement in the security situation in the past five years, many areas of the country are now stable and safe for birders to return.
		Colombians are extremely hospitable towards foreigners and they will make certain that your impression of their beautiful country is something different to what is often presented in the international press.
		ACT is seeking support for the development of the special conservation and sustainable management area in the Fragua River region of the Alto Caqueta in the foothills of the Colombian Amazon, known as the Niñeras and Fraguas Special Conservation and Sustainable Management Areas project (or the Parks Agreement).

		At the end of the book there are two identification plates by Chris Rose which provide invaluable assistance on field identification features.
		Appendices provide data on length, weight, breeding details, status and conservation, and the meanings and derivations of grebe names.
		By depicting each grebe in its natural habitat, Rose fills each page with colour and light, magnificently evoking the water-based world of these beautiful birds.

		I am a Colombian who has lived in Washington D.C. for 35 years and it is so refreshing to find something positive about my country.
		Please excuse me for taking the liberty of giving you two small suggestions: the first one is that you include the Colombian names of the birds.
		The second one is due to the fact that I am a Spanish teacher and it refers to the "gender" of nouns in Spanish.
